I hate them, they are overpriced junk, you could put UNTs on your units for cheaper than purchasing those stats, also the stats have I high failure rate, I thought I was the only one but at a recent control training class we found another company that uses them alot, we asked them about failure rates because of the rates we have seen and they said they fun 30%+ failure rate.

Of course we have a couple of jobs where we have had only 4 or 5 failures over a course of 5 years on 18 units total, some jobs a little less, but wait til everyone else posts their opinion.

If they are already there use them , REVELATION software is around $400.00 list $. The EMBEDDED 2040 is available in 2 versions REGULAR and ADVANCED and neither 1 has a $ in the latest $ book, have to call the factory for $ing however based on the QD2020 site communicators list $ would be in the $2,300.00 + range.

FAILURE rates on the TCS I have sold / installed are next to nothing, as for their sensors I finished a service inspection on a 14 year old system that is all TCS sensors 2 out of 147 needed recalibration after all that time.

Thanks fellas for the comments. But now I have to ask about the Rev Pro software vs. the QD2040 embedded webserver. Isn't the Rev Pro software DOS based? Is it CLUI or is it graphics? I appreciate the help.

P.S. We've had the stats installed for about 4 yrs. and we haven't had any failures yet . . . knock on wood . . .
